Definitions

  • the invention relates to a motor vehicle, in particular a passenger car, with an engine fan for cooling an internal combustion engine.
  • the voltage of the motor blower is controlled by a cooled linear regulator.
  • the internal combustion engine of a motor vehicle is cooled by a water circuit to which a motor fan belongs.
  • the engine fan is driven either electrically or mechanically while the engine is running. When stopping the engine, there is usually a lag of the then electrically operated engine fan with appropriate engine temperature.
  • the engine fan has an electric motor whose power is usually adjustable in stages.
  • the power control is done with parallel or serial switches or relays.
  • stepless control is also known with controllers based on pulse width modulation, the so-called PWM controllers.
  • the PWM regulators thus operate in the engine compartment with its often quite high temperatures.
  • the US 2003/0058617 A1 describes a linear controller for the speed control of the blower of an air conditioner in a car. Since the temperatures in the vehicle interior are generally much more moderate than in the engine compartment, it is sufficient for the US 2003/0058617 A1 that the linear regulator for its cooling in the Air flow of the air conditioning is placed, and here, for example, close to the rotor blades of the fan. Similar applications of the linear regulator for air conditioning systems also reveal the US 2005/02642253 as well as the EP 1475884 A2 ,
  • a motor vehicle with a water circuit for cooling its internal combustion engine is proposed.
  • the water cycle includes an electrically powered motor fan associated with a linear regulator, i. h., the voltage of the motor blower is controlled by the linear regulator.
  • the linear regulator is thermally coupled to the water cycle.
  • the proposed solution allows stepless regulation of the motor fan. Due to the stepless controllability results first a minimal noise with minimal load on the battery. Compared to a control with relays results in greater reliability through fewer electrical connections, fewer cables and by the presence of overheating protection fewer failures with less risk of fire. Also, the use of a linear regulator instead of relays leads to about 50% reduced weight at least 80% lower Space required at less than half the price. Furthermore, the installation costs are lower and a diagnosis in case of failure can be realized.
  • the linear regulator Compared to PWM controllers, the linear regulator has a much better electromagnetic compatibility, since the former are disadvantageously clocked at 20 kHz.
  • the PWM regulator therefore requires extensive measures to ensure electromagnetic compatibility, which makes the PWM regulator a component that today is about three times as expensive as a linear regulator.
  • the solution allows for the first time a stepless control of the engine fan in small and mid-range vehicles at acceptable prices, but in turn requires an intervention in the complex cooling system of the internal combustion engine by dissipating the power loss of the linear regulator to the water cycle.
  • the linear regulator is in thermal contact with a water conduit of the water cycle. This makes it possible to choose a position of the linear regulator close to the engine fan in the design of the vehicle in order to reduce the wiring overhead.
  • the water pipe has a recess into which the linear regulator or a cooling block assigned to the linear regulator is partially embedded.
  • the water pipe consists for example of die-cast aluminum, in the recess of the linear regulator or its cooling block is inserted and sealed accordingly.
  • the linear regulator is thermally coupled to the cooling liquid of the water cycle, which is more efficient than cooling via the medium air.
  • the linear regulator stands in thermal contact with a radiator associated with the water cycle and containing the cooling fluid.
  • the linear regulator can rest directly on the (water) cooler.
  • the linear regulator is arranged in the air flow of the engine blower. It is insofar made an air cooling, wherein the intervention in said water cooling circuit is minimal.
  • Another aspect of the invention relates to a water cooler, which is designed for releasable connection to a linear regulator, wherein the linear regulator is used to control the motor fan.
  • the water cooler can be prepared in that the linear regulator is inserted into the water cooler or attached via a clip connection with this.
  • An embodiment of the water cooler has a releasably connected to him linear regulator.
  • the linear regulator can be mounted on one of the side coolant tanks of the water cooler. Because of the lower temperatures of the coolant, the coolant outlet side end tank is preferably selected here.
  • Another aspect of the invention relates to a CRFM module having an engine fan and a water cooler as described above.
  • results from the made Function integration reduces space requirements for engine compartment components with greater freedom in developing a new vehicle.
  • FIG. 1 a motor vehicle 1 in plan view.
  • the motor vehicle 1 has an internal combustion engine 2, in front of which the water cooler 3 and the air conditioning condenser 4 are arranged.
  • a motor fan 5 is provided for the radiator after a shutdown of the motor vehicle 1.
  • Water cooler 3, air conditioning condenser 4 and engine fan 5 may be individual components for the separate cooling circuits, or be components of a CRFM module (English: condenser radiator fan module) 6, as indicated by the dashed line.
  • the CRFM module 6 cools the engine 2 in a known manner via the water pipe 7 with cooling liquid.
  • a linear regulator 8 is inserted in the water pipe 7, a linear regulator 8 is inserted.
  • the linear regulator 8 is connected via an electrical line 9 to the CRFM module 6 and regulates the fan or motor fan 5 continuously.
  • the fan noise during caster and the load on the battery (not shown) is reduced to a minimum. This succeeds despite the sometimes high temperatures in the engine compartment with the linear regulator 8, which can be sufficiently cooled by the coolant in the water cycle.
  • FIG. 2 shows a water cooler 3, an end tank 12, 13, a linear regulator 8 is screwed. Since the coolant inlet 13 in FIG. 2 right and the coolant outlet 14 is right, this is chosen because of the lower temperatures of the coolant outlet side end tank 12.
  • the water cooler has a well adapted to the dimensions of the linear regulator 8 depression (not shown), which receives the linear regulator partially.
  • the water cooler 3 may be part of the CRFM module 6 of FIG. 2 be.
  • FIG. 3 This has a recess 10, in which the cooling block 11 of the linear regulator 8 is inserted so that it is flowed around directly by the cooling liquid of the water cycle.
